From dd1fac6ae648cac4e92ccc829e94750ddfed5e52 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Wed, 31 Jan 2024 18:02:22 -0500 Subject: nfs: adapt to breakup of struct file_lock Most of the existing APIs have remained the same, but subsystems that access file_lock fields directly need to reach into struct file_lock_core now.
